best cosrx products

What are the best Cosrx products? Boy, was it hard to choose. I feel like a lot of Korean skincare is about moisture, moisture and more moisture only. Cosrx is different. It gives you plenty of moisture alright, but also the right actives to deal with blackheads, fight wrinkles and fade away dark spots. Cool, right? So, where can you find these skincare superstars? Here are the best Cosrx products for every skin type and need:

What Are The Best Cosrx Products?

Cosrx The Vitamin C23 serum

Best For Brightening: Cosrx The Vitamin C 23 Serum ($25.00)

Cosrx The Vitamin C23 Serum contains one of the highest concentrations of Vitamin C (L-Ascorbic Acid) I’ve come across in skincare. This powerful antioxidant fights free radicals, boosts the production of collagen and even fades away dark spots. High concentrations can be irritating, so Corsx added natural oils and hyaluronic acid to the mix to keep your skin soft and hydrated while Vitamin C does its job. The silicones texture glides smoothly on the skin and is a pleasure to use.

P.S. If you have sensitive skin, Corsx also has a 13% Vitamin C Serum that’s more suitable for your skin type.

Available at: Beauty Bay, Cult Beauty, Sokoglam, Stylevana, and Yes Style

Active ingredients: 23% L-Ascorbic Acid (Vitamin C) and Hyaluronic Acid.

Benefits: Prevents wrinkles and fades away dark spots.

Cons: High concentrations of Vitamin C can be irritating.

Skin type: Best for dry skin.

Fragrance-free: Yes.

cosrx low ph good morning gel cleanser 02

Best For Cleansing: Cosrx Low-pH Good Morning Cleanser ($14.00)

Ever wondered why a lot of cleansers leave your skin feeling super tight? It’s all in the pH. If it’s higher than 6.5, it’ll destroy your skin’s acid mantle and weaken its protective barrier so that moisture can freely fly out into thin air. Cosrx Low-pH Good Morning Cleanser has a skin-friendly pH of 5: it gently removes all traces of dirt, impurities and even makeup without compromising your skin’s acid mantle. Its foaming texture is better for oily skin but anyone can use it.

Available at: Beauty Bay, Dermstore, SokoGlam, Ulta and Yes Style

Active ingredients: Cocamidopropyl Betaine, Sodium Lauroyl Methyl Isethionate.

Benefits: Cleanses skin and removes impurities.

Cons: May be a little drying for dry skin.

Skin type: Oily and acne-prone skin.

Fragrance-free: Yes.

Best For Oily Skin: Cosrx BHA Blackhead Power Liquid ($22.00/£15.94)

Salicylic acid is a must for oily, blemished skin. It gets inside the pores, exfoliating it of all the gunk that’s clogging them up and giving you pimples and blackheads. But what if SA doesn’t agree with your skin? Are you doomed to dealing with blackheads forever? Nope. Cosrx BHA Blackhead Power Liquid uses benzyl salicylate, a gentler form of salicylic acid that gets the job down (more slowly) without side effects. It’s the perfect alternative for anyone with fungal acne or that simply can’t tolerate SA. Plus, it has a dollop of niacinamide to help keep skin blemish-free.

Available at: Dermstore, iHerb Ulta and Yes Style

Cosrx Galactomyces 95 Tone Balancing essence

Best For Dry Skin: Cosrx Galactomyces 95 Tone Balancing Essence ($24.00)

Korean women are obsessed with galactomyces ferment filtrate – for a reason. Studies show this yeast extract can strengthen your skin’s protective barrier, so it can better withstand attacks from the sun, the cold weather, harsh skincare products and co. Plus, Cosrx Galactomyces 95 Tone Balancing Essence is loaded with niacinamide, a skincare superstar that does everything: hydrates skin, strengthens the protective barrier, soothes irritations, fades away dark spots, fights wrinkles and even soothes acne! If you need to add a toner/essence to your winter skincare routine, this is it.

Available at: Beauty Bay, Sephora, Stylevana, and Yes Style

Active ingredients: Galactomyces ferment filtrate and niacinamide.

Benefits: Hydrates and soothes skin.

Cons: Packaging isn’t the prettiest.

Skin type: All skin types can use it, but it’s best for dry and sensitive skin.

Fragrance-free: Yes.

Best Moisturiser: Cosrx Advanced Snail 92 All In One Cream ($22.00/£17.47)

I’m not of hug fan of jar packaging, but I’ll make an exception for Cosrx Advanced Snail 92 All In One Cream because there’s nothing that can spoil here. It’s a basic concoction of snail extract and hyaluronic acid. Snail extract is one of the most moisturising substances on this planet: it makes even the driest of skin soft and smooth quickly and helps wounds heal faster. Hyaluronic acid attracts water to the skin and binds it there. It’s so powerful it can hold up 1000 times its weight in water! This is a great moisturiser for all skin types, including oily.

Available at: iHerb, Ulta and Yes Style

Is Cosrx Cruelty-Free?

Yes, Cosrx is cruelty-free. They don’t test on animals and don’t sell in countries where animal testing is required by law.

What Are The Pros Of Cosrx Skincare?

Cosrx is my fave Korean skincare brand. While most Korean brands focus on hydration and innovative gimmicks, Cosrx follows the science. It utilises actives like retinol, Vitamin C and AHAs that can do what they say on the tin and deliver brighter, plumper, younger-looking skin. The best part? Cosrx keeps it all affordable, so everyone can enjoy their best skin day, no matter what your budget is.
